The drones will have to provide high-precision aerial images, with a ground resolution of 6 centimeters per pixel. This data will be used to generate three-dimensional models and detailed topographic maps, incorporating the relief and existing structures with a planimetric and altimetric accuracy of 10 centimeters.

The program is divided into three technical missions, including the creation of reference databases and the analysis of the evolution of the coastline compared to administrative archives. Experts will be tasked with calculating the "cubatures" to precisely measure the volume of sand and material movements on the coastline.
